Cut-price American butter sold at Pak'nSave supermarkets is causing confusion among New Zealand shoppers due to packaging that closely resembles local products. The Burtfield's & Co brand, imported in bulk by Dairyworks and repackaged at their Canterbury facility, is wrapped in familiar yellow paper and sold in 500-gram blocks that undercut New Zealand butter on price.

Federated Farmers dairy chair Karl Dean has called for clearer country of origin labelling, noting that many consumers are missing the small print indicating the product is imported from the United States. Unlike other international butter brands that typically come in distinctive foil packaging and smaller premium blocks, this American butter mimics the traditional paper packaging style familiar to Kiwi consumers. Some shoppers have only discovered they purchased imported butter after opening the blocks at home, finding the pale colour different from the sunny yellow they expect from New Zealand products.
